Structure design and steady-state thermal analysis of materials thermodynamic parameter testing device

为解决现有管式炉在高温烧结时存在不能测量温度和变形的问题,以现有管式炉为基础,设计并改进一种用于测试高温条件下材料热力学参数的装置。通过ANSYS Workbench对该测试装置的管式炉结构进行建模,采用实体单元对结构进行模拟;对管式炉结构进行稳态热分析,并得到法兰的温度,评估配置冷却系统的必要性;利用参数优化方法,得到法兰2右端温度为40℃时冷却系统需要具备的对流传热系数,为冷却系统中模温机的选型提供指导。

In order to solve the problem that the existing tube furnace can not measure temperature and deformation during high temperature sintering,a device for testing the thermodynamic parameters of the material under high temperature conditions is designed and improved based on the existing tube furnace.The tube furnace structure of the test device is modeled by ANSYS Workbench,and the structure is simulated by solid elements.The steady-state thermal analysis of the tube furnace structure is carried out,the temperature of the flange is obtained,and the necessity of cooling system is evaluated.Using the parameter optimization method,the convection heat-transfer coefficient required for the cooling system is obtained when the temperature at the right end of the flange 2 is 40℃,which provides guidance for the selection of the mold temperature machine in the cooling system.
